Digital BW, The Print

I have been using the cfs system with photo black for over 1 1/2 and
all was well till I decided to switch to the matte black ink. I
ordered just the cfs portion of the matte blk ink set. I got a clear
ink cartrridge loaded with ebony, cfs tube and a bottle of ebony ink.
When I installed the ink, the printer was still showing photo blk,
after contacting MIS, it turned out that the chip was wrong and they
sent me a replacement chip.

When I replaced the chip, I was getting weird colors, after contacting
MIS, the possibility of ink contamination came up, so I decided to
change all the ink bottles with new bottles with new ink and let the
print test pages for three weeks, enough of the ink was used that all
the cartridges had fresh ink. I did my test again and to my surprise,
the same results. Weird colors. I get a lot of burned/over exposed
colors on shadow areas especially on skip tone.

I contacted MIS again, and they mention contamination again, after I
explained all of what I did and may be the driver is holding the old
settings, so un install the driver and re install a new one (which I
did and no help). I finally asked them to send me a new chip and is
sitting on my desk. The chip says regular on it and I think I need the
cfs chip, so another call to MIS next week…


Thanks for reading, now my question: could this be the cartridge
that's bad, MIS was insisting that it is not. One final note, I put in
the old photo blk and all is fine!! I am at loss and would appreciate
and all help
